Recipe Objective

Binding or concatenating rows or columns of two different dataframes is an important task to perform in data manipulation. we use rbind() and cbind() function to carry out this task on rows and columns respectively. ​

This recipe demonstrates the concatenate 2 dataframes using rbind() and cbind() functions.

  1. rbind() function combines the rows of two dataframes of equal length.
  2. cbind() function combines the columns of two dataframes of equal length.

Step 1: Creating two Dataframes

We use data.frame() function to create DataFrames

Name = c("Ram", "Fredo", "Geeta", "Jessica") rank = c(3,4,1,2) marks = c(50, 45, 95, 80) dataframe1 = data.frame(Name,rank,marks) print(dataframe1)
     Name rank marks
1     Ram    3    50
2   Fredo    4    45
3   Geeta    1    95
4 Jessica    2    80

Name = c("Suresh", "Ramesh") rank = c(6,5) marks = c(40,43) dataframe2 = data.frame(Name,rank,marks) print(dataframe2)
    Name rank marks
1 Suresh    6    40
2 Ramesh    5    43

Step 2: Using rbind() to concatenate 1 and 2

Syntax: rbind(dataframe1,dataframe2) ​

# combining the rows of the two dataframes dataframe3 = rbind(dataframe1,dataframe2) print(dataframe3)
     Name rank marks
1     Ram    3    50
2   Fredo    4    45
3   Geeta    1    95
4 Jessica    2    80
5  Suresh    6    40
6  Ramesh    5    43

Step 3: Using cbind() to concatenate 1 and 2

Syntax: cbind(dataframe1,dataframe2) ​

# combining the columns of the two dataframes dataframe4 = cbind(dataframe1,dataframe2) print(dataframe4)
     Name rank marks   Name rank marks
1     Ram    3    50 Suresh    6    40
2   Fredo    4    45 Ramesh    5    43
3   Geeta    1    95 Suresh    6    40
4 Jessica    2    80 Ramesh    5    43
